This is Kalypso (left) and her sister Cassandra (right). I haven't drawn Kalypso in a while and haven't ever drawn Cassandra. Kalypso is a pirate, once the heir to the throne in the Elvin Nations. Cassandra is her overly flirty (or slutty, your pick) sister. Kalypso was once a reserved shy young lady, but after enemy forces attacked her home and she came to be part of a pirate crew, she outgrew it quickly. Her sister Cassandra was believed to be the only survivor of the royal family and decided she would take charge of the Elvin nations. Cassandra enjoys causing her sister distress and pain, believing that Kalypso had no right to run away from the attack. As you can see, Kalypso hates her sister with a passion as well.
